Description

Technical Field

[0001] The utility model relates to the technical field of road detection, in particular to a road engineering horizontal detection device. Background Technique

[0002] The commonly used method for measuring the pavement flatness is generally to place a three-meter straightedge on the pavement to be detected, and then find the maximum gap between the three-meter straightedge and the pavement, and analyze the flatness of the pavement from the size of the gap.

[0003] The patent document with the publication number of CN213273993U discloses a spirit level for road detection, including a first outer shell. A first rotating bolt is arranged above the first outer shell, and a second outer shell is arranged above the first rotating bolt. At the same time, the second outer shell is connected to the first outer shell through the first rotating bolt. A measuring scale is arranged above the first outer shell, and first clamping blocks are arranged on both sides of the measuring scale. The first clamping blocks are installed in cooperation with first clamping grooves, and the first clamping grooves are respectively opened on both sides of the inner wall of the first outer shell. A marking pen is arranged inside the first outer shell, and a baffle is arranged in front of the marking pen.

[0004] However, the above device has the following problems when in use; when the above spirit level is in use, like the common spirit level, it is necessary to manually observe the maximum gap between the spirit level and the ground, and then manually insert a feeler gauge into the gap for reading, with low efficiency. And the existing horizontal measurement generally directly leans the spirit level against the road for measurement. However, due to the unevenness of the road surface, the raised parts will affect the normal placement of the spirit level, thus affecting the measurement results. Content of the Utility Model

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Please refer to Figures 1 to 5 , a road engineering horizontal detection device, including a first level 1 and a second level 2. The first level 1 and the second level 2 are connected by a hinge 5. The first level 1 and the second level 2 can be unfolded and stored, so as to facilitate carrying. Preferably, the first level 1 and the second level 2 should be provided with matching parts for fixing at corresponding positions to ensure the stability of the unfolded state. Since it is prior art, it will not be elaborated here.

[0027] Level bubbles 3 are inlaid and installed on both the first level 1 and the second level 2. The level bubbles 3 can be used to judge whether the device is placed horizontally, so as to ensure the accuracy of the measurement data;

[0028] Support blocks 4 are fixedly installed on the edges of both the first level 1 and the second level 2. When in use, instead of the level directly contacting the ground, the support blocks 4 directly contact the ground. As long as multiple support blocks 4 are on the same horizontal plane (observed through the level bubble 3), the horizontality of the device placement can be ensured to ensure the measurement effect;

[0029] Conversion components are arranged inside both the first level 1 and the second level 2. The conversion components are used to convert the unevenness of the ground into its own height difference, so as to be more convenient for visual observation;

[0030] The conversion component includes an exposed rod 6, a moving ring 7, and a contact rod 8. The moving ring 7 is slidably installed inside the first level 1 and the second level 2. The exposed rod 6 and the contact rod 8 are respectively fixedly installed on the upper and lower sides of the moving ring 7 and both protrude from the corresponding sides.

[0031] Under the action of gravity, the contact rod 8 will move downward. The road surface to be detected can support the contact rod 8. Due to the uneven ground, the heights of the support points corresponding to different contact rods 8 are different. As a result, the height of the exposed rod 6 descending (or ascending) is also different. The unevenness of the bottom plane can be judged by observing the height of the exposed rod 6.

[0032] Accommodation cavities 9 for the moving ring 7 to slide are respectively provided inside the first level 1 and the second level 2. When the contact rod 8 moves, the moving ring 7 moves inside the accommodation cavity 9, which can ensure the smoothness of the movement.

[0033] Reading components are provided on both the first level 1 and the second level 2. The reading components can read the exposed length of the exposed rod 6, thus facilitating recording and subsequent calculation activities.

[0034] The reading component includes an observation piece 10, a mounting table 13, and a rotating shaft 16. The mounting table 13 is slidably installed on the first level 1 and the second level 2. A rotating shaft 16 is rotatably installed on the mounting table 13, and an observation piece 10 is fixedly installed on the rotating shaft 16. Scale lines are evenly arranged at equal intervals on the observation piece 10.

[0035] By observing the highest and lowest points of multiple exposed rods 6, moving the observation piece 10 to the position of the corresponding exposed rod 6, then corresponding the height of the exposed rod 6 with the scale on the observation piece 10, using the hand or a corresponding sliding pointer (not shown in the figure) to hold the corresponding position, and rotating the observation piece 10 around the rotating shaft 16 until the observation piece 10 is adjusted to a suitable observation angle, and reading the scale on the observation piece 10, the uneven data of the road surface to be detected can be obtained, which is more convenient to use.

[0036] A slider 12 is fixedly installed at the bottom of the mounting table 13. Sliding grooves 11 for the corresponding sliders 12 to slide are respectively provided on the first level 1 and the second level 2. When the observation piece 10 moves, the slider 12 moves inside the sliding groove 11.

[0037] The zero scale line on the observation piece 10 is at the central position, and the observation piece 10 is divided into an upper convex indication area 14 and a lower concave indication area 15 by the zero scale line. The indications in the convex indication area 14 are positive numbers, and the indications in the concave indication area 15 are negative numbers.

[0038] When the lower surface of the contact rod 8 and the lower surface of the support block 4 are in the same plane, the upper surface of the exposed rod 6 is flush with the zero scale line on the observation piece 10.

[0039] When the road surface to be detected is parallel, at this time, the upper surface of the exposed rod 6 is at the position of the zero scale line. When the road surface to be detected is concave, the contact rod 8 will descend, and the exposed rod 6 will then be at the position of the concave reading area 15. When the road surface to be detected is convex, the contact rod 8 will be pushed up, and the exposed rod 6 will be at the position of the convex reading area 14. The measurement range of this device is more accurate and convenient for daily use.

[0040] A fixed sleeve rod 17 is fixedly installed on the rotating shaft 16. Two shielding pieces 18 are fixedly installed on the mounting table 13 at corresponding positions. The shielding pieces 18 are on the movement track of the fixed sleeve rod 17. Through the cooperation of the fixed sleeve rod 17 and the shielding pieces 18, the rotatable angle of the observation piece 10 can be controlled, so that the observation piece 10 can be stably maintained in a state perpendicular or horizontal to the mounting table 13, which is convenient for reading and storage activities (to avoid excessive protrusion and cause unnecessary damage during movement).

[0041] The working process of the present utility model;

[0042] Deployment and fixation: The user first unfolds the first level 1 and the second level 2 through the hinge 5, and makes them form a straight line through the fixed fitting on the first level 1 and the second level 2 (although the specific fixing method is not described in detail, it can be understood as some common locking mechanisms such as buckles or locking screws).

[0043] Placement and calibration: Place the device steadily on the road surface to be detected, ensuring that the support block 4 is in contact with the ground. The support block 4 is designed to prevent the level from directly contacting the ground and reduce errors. By observing the spirit level 3, adjust the device until the bubble in the spirit level 3 is at the central position to ensure that the device is in a horizontal state.

[0044] Measurement and reading; After placement, under the action of gravity and support force, the contact rod 8 will move. The road surface to be detected can support the contact rod 8. Due to the uneven ground, the heights of the support points corresponding to different contact rods 8 are different, and thus the descending (or ascending) height of the exposed rod 6 is also different. The uneven changes of the ground can be intuitively reflected in the height difference of the exposed rod 6.

[0045] When the road surface to be detected is flat, the lower surface of the contact rod 8 should be in the same plane as the lower surface of the support block 4. At this time, the upper surface of the exposed rod 6 is aligned with the zero scale line on the observation piece 10.

[0046] If the road surface is sunken, the contact rod 8 will descend, causing the exposed rod 6 to enter the concave scale area 15 on the observation piece 10, showing a negative scale.

[0047] If the road surface is convex, the contact rod 8 will ascend, causing the exposed rod 6 to enter the convex scale area 14 on the observation piece 10, showing a positive scale.

[0048] By observing the highest and lowest points of multiple exposed rods 6, moving the observation piece 10 to the position of the corresponding exposed rod 6, and then corresponding the height of the exposed rod 6 with the scale on the observation piece 10, the user can adjust the angle of the observation piece 10 by rotating the rotating shaft 16 to more conveniently read the scale value.

[0049] After that, multiple groups of data can be recorded.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
